Carl Laundrie, a spokesman for Flagler County, told The Florida Times-Union that the crash happened Saturday afternoon. The Florida Highway Patrol identified the pilot as 58-year-old William Walker of Cookeville, Tenn.

Walker was flying a Yak-52, which was originally designed as a Soviet warplane and now is popular at airshows.

It wasn't immediately clear what caused the crash. The Federal Aviation Administration and National Transportation Safety Board are investigating.

The Wings Over Flagler Fly-In continued Sunday with fly-overs but no aerobatics.
